摘要
港区交通不同于一般城市交通,它服务于集疏运交通,主要以货运为主,大型车比例较高。大型车行驶过程中和停车需要较大的车道空间,转弯时需要占用较大面积,同时,大型车行驶速度较慢且加减速性能较差(特别是在超载的情况下),导致驾驶员需要较长的反应时间。从车辆特征以及交通流特征2个角度论证港区道路的交通特性,为道路的分级、交叉口以及出入口的设计提供基础数据。
Port traffic is different from common urban traffic,because it mainly serves for collecting and distributing traffic mainly with freight traffic and high proportion of large vehicle. The large vehicle needs larger lane during driving and parking,and will occupy a large area when turning. Meanwhile,due to the large vehicle slow speed and its poor acceleration & deceleration performance(especially in the case of overloading),the drivers have to take longer reaction time. Traffic characteristics of harbor roads are proved from two aspects: vehicle characteristics and traffic flow characteristics,and the basic data are provided for road grading,intersections and entrances designs.
